i just recently filled up my 2002 ba xr6 ute today and for some reason my fuel tacho isnt working properly??? its very very very slowly goin from E to F on the tacho??? im s**t bricks please help???

id also like to know is there anyway possible to find out if you can do a self ecu check to see if any codes come up indicating theres a problem with something??? like by connecting any wires or will i have to take it to ford??? ecause my abs sensor is shot and i want to see if i can do a self check
if yes can i have a list of codes or numbers with the problems or parts that are being checked???

im freaking out
